The Modern Synthetic Theory of Evolution combines Darwin’s natural selection with Mendelian genetics, emphasizing evolution as changes in allele frequencies within populations. It highlights five mechanisms: mutation, recombination, natural selection, genetic drift, and gene flow. These processes generate and redistribute genetic variation, driving gradual evolutionary change. The theory integrates population […]
Natural selection is the process where individuals with advantageous traits are more likely to survive, reproduce, and pass on those traits to offspring. It acts on phenotypic variation within a population, which arises from genetic differences. Favorable traits increase in frequency over generations, while less advantageous traits diminish. This mechanism […]
Microevolution and Macroevolution are two scales of evolutionary change that describe different processes and outcomes in the evolution of organisms. Microevolution refers to small, gradual changes that occur within a population over a relatively short period. These changes typically involve alterations in allele frequencies due to natural selection, genetic drift, […]
Neo-Darwinism, also known as the Modern Synthesis, is the theory of evolution that combines Darwin’s natural selection with Mendelian genetics. It incorporates the understanding of genetic variation, mutation, gene flow, and genetic drift as the mechanisms driving evolutionary change. Neo-Darwinism emphasizes that evolutionary change is a gradual process, shaped by […]
Darwinism refers to the theory of evolution by natural selection, originally proposed by Charles Darwin. It suggests that organisms with traits better suited to their environment are more likely to survive and reproduce, passing these beneficial traits to their offspring. This process leads to gradual changes in populations over time, […]
